UNITED STATES PATENT OFrIca JAMES P; ARiNOLDfOF LOUISVILLE, KENTUCKY;

IM PROVEMENT IN 'IPRESYS'ES.

' Specification forming part of Lettrrs Patent No. I 2,615, dated April 3, 1855.

To all whom it may concern:

Be 1t known that I, JAMES P. ARNOLD, of -Lou1sv11le,'-in the county of Jefferson and State of Kentucky, have invented certain new The nature of my invention relates tothe method of applying the gradually-increasing power, with the proportionate diminution of speed, of a system of cone-pulleys through the medium of an automatic shipper worked' with the platen to the operating of a hemppress, so that the'power in pressing shall increase with the resistance on the platen, and the platen run back with a highly-increased velocityover that of its forward motion when the bale is roped and ready to be removed A represents the bottom sill, and B' the head-bloclgfirmlyunited by the jambs or side pieces, 0 0;.

V1) is the platen or follower on theend of the "screw shaft or rod'E. I

' F F are the cone-pulleys, and G G G G the doors or aprons throughwhieh the press is charged and the bale delivered. The doors next the sillare double when closed,an'd are hung on strap-hinges extending across the jamb, and are held in their places byune'ans.

of a hook, latch, or other proper catch, One closes from right to left, the other from left to right, and thus oneentircly'overlaps the other and makes a double door, which gives it the necessary strength to withstand the pressure of the platen upon the hemp to be baled up.

, By inspection of the drawing Fig. 1 it will be seen that the open door on the left is rec'cssed,'a, for the purpose of presenting a plane,

surface when closed. r

H, Figs. 1, 2, is asliding bar supported in slotted brackets J' J, which. may be fastened 3 represents a side-'elevar the platen upon it.

- to the joist or ceiling above,and I I l are other brackets, suspended in similar 1nanner,,for making proper supports for theconepulleys F F. a

K K aretwo small bevel ,gearavheels loose on theirshafts, but thrown into or out of gear with the larger bevel-wheel, K, at pleasure, by means of the double clutch .L, Figs. 2, 3,

' operated by a lever, M, Fig; 2, so as to give the necessary'forward or backwardmotion to the press. The cones by this means may be kept in constant motion and their power applied by means of the clutch at pleasure to the ,working of the platen either forward or back. N is a substantial cross-beam for supporting the weight of the wheel, 0, screwshaft E, and follower D. It is properly secured to the jam'bs or side pieces, 0 O. The large bevelwheel K is attached to the upper end of a shaft,Q, and on the lower end of said shaft/1s secured a spur-wheel, P, working into and giving motion to the'main driving-wheelO, through the hub or center of which the-screw rod or shaft 15- passes in a femalescrew. and thus gives motion to the screwrod itself and R R are the bearers or boxes in which the journals of the shaft carrying the spur-wheels K K and clutch L are supported.

S, Fig. 1,is a hook on the platen or follower, to which the shipper-ehain is fastened, and T the hooks or fastenings by which the doors are secured when closed. The shipper-chain U, being fastened to the hook on the platen, passes up and over the friction-pulleys V, and being fastened to the shipper \V where it crosses it,

and,after passing over the rear pulley V, terminates or may terminate in aweight or counterpoisefthe office of which will be mentioned in the operation of the press. The shipper W is secured to the sliding bar II, anda fork on each end of the, shipper straddles the belt X, which passes around the cone-pulleys, so that as thebar H is moved toward or from the press it 'carrieswith it the shipper V and the belt X, thus changing the relative diameters, and consequently the speed, in the ratio of the re- Y are the driving-pulleys, throughwhieh, orthe crank near to them, powerinay be applied to the press, and Z are frictionrolls to keep thejfollower from rubbing against thejambs'or sides of the'press, so as to bind or cramp therein.

The operation of the press is as follows: The box being properly charged, the platen run up to or near the beam N, the doors shut and secured, the chain U being first hooked to the follower, and the belt-shipper and bar run out the extreme end of the cone-pulleys, the clutch is thrown in%o gear with one of the spurs K, and the fo lowercommences to descend upon the material to be pressed, and as tied up, and ready to be removed, the chain U is freed from the hook S, and by means of a weight or otherwise the shipper-bar and belt are carried back to the extreme ends of the cones, and the follower is run upwith a fourfold increased speed, and the press is ready for another charge and a similar operation.

4 Having thus fully described-the nature of my invention, I would state that I am aware that conical pulleys and a traveling belt thereon have been used for various purposes where speed and power are required at variable stages. These I do not claim; but

What I do claim as new,and desire to secure by Letters Patent, is-

Operating the shipper that moves the belt along the cones by the descent of the platen while pressing, so that the power shall be increased with the resistance until the material is pressed, and then allowing the shipper to run back at an increased velocity when the bale is ready to be removed, substantially as described.
